DESCRIPTION

The glmatrix program draws dropping characters similar to what is seen
in the title sequence of the Wachowski brothers’ film, "The Matrix".
Also see xmatrix(6) for a 2D rendering of the similar effect that
appeared on the computer monitors actually in the movie.

OPTIONS

glmatrix accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-install
Install a private colormap for the window.
-visualvisual
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual.
-delayusecs
The delay between frames of the animation, in microseconds:
default 30000.
-speedratio
How fast the glyphs should move; default 1.0. 2.0 means twice
as fast, 0.5 means half as fast.
-densitypercentage
The approximate percentage of the screen that should be filled
with characters at any given time. Default 20%.
-no-fog By default, glyphs are dimmer the farther away they are. This
argument disables that.
-no-waves
By default, waves of color roll down the columns of glyphs.
This argument disables that.
-binary Instead of displaying Matrix glyphs, only display ones and
zeros.
-hexadecimal
Instead of displaying Matrix glyphs, display hexadecimal
digits.
-dna Instead of displaying Matrix glyphs, display genetic code
(guanine, adenine, thymine, and cytosine.)
-wireframe
Just draw boxes instead of textured characters.
-fps Display a running tally of how many frames per second are being
rendered. In conjunction with -delay0, this can be a useful
benchmark of your GL performance.

ENVIRONMENT

DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
